    tell me your AP estimated torque values

    Hey guys - just wanted to get your feedback on the estimated torque you are seeing when datalogging. As far as power upgrades, my car just has Mountune IC, 1 step colder plugs, and Borla S-Type catback. I have worked with 2 of the bigger name tuners over the last 2 years and one's e-tunes peak at about 380lb-ft while the other's peak at over 435lb-ft, both on 93 oct.

    I am curious about what numbers you guys are seeing with similar modifications. Is there anything to worry about with big numbers like 435lb-ft? Thank you in advance!

    John

    I’m just running 94 octane. I find that the torque stays around 450 but Hp can range from 420-470 as seen in picture. Many a V8 car always say to me holy F$&k what do you have in there!

    Yeah but the AccessPort est horsepower and torque figures are total rubbish according to tuners.

    Depends on who else drives your car and how they drive it. My tuner (Adam) generally keeps WHP and torque around 380 (on E-30) at least that is what he did two years ago when he finished my latest tune. I think the greatest danger is going full throttle at low speeds in too high of gear. You are in danger of putting too much load on the rods/bearings and that situation also lends itself to the possibility of low speed detonation.
    In my case my wife also occasionally drives my car. When she wants to pass she steps on the gas no matter what gear she is in. At 380 WHP I still have some buffer to what the engine will take when loaded at full throttle in too high of gear. In my opinion at 435lb-ft you are running on the "edge" and should start thinking of running forged internals or limit your torque to 400 max.

    I read somewhere that the values have a +/- of 3-5% If you use the drivetrain lose of 15% I’m right around 400 hp/torque.

    Are you guys on stock blocks/heads/headstuds with that much HP/TQ? Isn't engine longevity a worry pushing that much power? I have a pretty conservative tune pushing around 350whp/380tq

    Edit: really depends on the day too, I was showing 420 hp yesterday on the AP.

    Thank you guys! Keep it coming!

    My understanding is that the 'estimated torque' is at the crank, not at the wheels. The tuner whose tune is at 380 tells me that's fine, that no further revisions are necessary. It feels barely better than stock, to be honest (I have never logged the OE tune). The 435 tune obviously feels a LOT stronger. And the torque values are higher all the way to redline so it's just plain stronger everywhere.
